Winchparts
I need a high ratio gearbox so I bought a cheap (au$70) electric boat winch for its 153:1 planetary gears. The motor shaft(top right) goes through the bearing in the housing (bit leftish) and becomes the "sun" gear which drives the three
planet gears (bot right). The planet gears are engaged in both the gear teeth moulded into the housing and the large gear they are in for the photo shoot.
These gears will have a slightly different number of teeth (different by 3?).

Not visible is the spline on the main gear (hidden by the planets) which take the spline which drive the winch spool. The spline in the spool retracts.

The shaft,spline and planets are steel but the large gear and housing appear to be an aluminium alloy (not sure) - wear could be a problem.
